I simply try to copy a few files/folders but Windows 7 calculates the time and the progress bar seems like Knight Rider. When I hit the Cancel button to cancel the operation, it won't be canceled for a long while. If it's USB memory then I simply unplug it. Copy, delete, move or cancel any operation, it randomly takes ages.
This is very annoying and I don't have any clue why Win Vista/7 do that? Is there any better application to replace Explorer for file copy/move/delete operations only?
